The lamp is working properly and is stuck to the body. After a 3-week vacation so that is also the tilting mechanism, no wear determine. This could be a bit more finely. Level one (easy straight forward) is actually getting too high, level 3 is too steep downward. Fortunately, skin stage two closely, but maybe that's when people of different body size (I'm 1,90m) somewhat differently. However, that fits so similar even when rummaging through a bag back in the dark and since the body size does not matter yes. So: The step difference is quite large, since you could still make improvements, so a star deduction. But otherwise there's nothing to complain about.
